Abstract
A drying material disposed in the passage of a compressed air system for removing moisture from air or gas includes a plurality of semi-rigid porous substrates impregnated with lithium chloride. The drying material is formed by preparing a saturated solution of lithium chloride and a nonflammable solvent. Porous substrata are contacted with the saturated solution to wet the substrata surface. The wet substrata are heated at a sufficient temperature for a sufficient duration to drive off excess liquid from the substrate. A desiccant comprising lithium chloride impregnated substrata is produced.
